Teaching and Learning in 3D Immersive Worlds: Pedagogical Models and Constructivist Approaches [PDF ebook] 

Virtual worlds are an area of growing interest in many sectors, including higher education. While Web-based tools have existed for years to help deliver course content, these tools have not traditionally provided means for creation of community with the embedded communication and collaboration necessary for successful teaching and learning. Teaching and Learning in 3D Immersive Worlds: Pedagogical Models and Constructivist Approaches examines successful implementation of social constructivist instructional design tenets in 3D virtual immersive environments. Authors share best practices, challenges, and advice to those working to utilize virtual environments in higher education and other venues. Readers will gain both a research background in the use of virtual worlds for teaching and learning and practical advice as they begin to design and implement these environments.
